Gardner Spring E38C Extension Spring 9.53 Lb 0.375 in Od

Product Description

The GARDNER SPRING E38C is a zinc-plated steel extension spring designed for light-duty tensioning and return-force applications across mechanical, HVAC, and industrial assembly systems. It features an outside diameter of 0.375 inches and a wire diameter of 0.0475 inches, with a spring rate of 8.01 pounds per inch and a maximum work load of 9.53 pounds. The overall free length is 2.0 inches, extending to a maximum of 2.89 inches under load. The cross-over end style allows for straightforward hook engagement in standard spring retention points. Installation is performed by mechanical technicians and field service professionals working on equipment that requires consistent return tension or controlled extension force.

This spring is suited for residential and light commercial mechanical assemblies where a small-diameter, low-load extension spring is required. The cross-over end configuration is common in HVAC damper linkages, control panel latches, door return mechanisms, and similar tensioning applications. Each order is packaged in a quantity of three pieces, making it practical for service kits and field stocking. The zinc-plated finish provides basic corrosion resistance in typical indoor mechanical environments.

Installation Notes

Extension springs under tension store mechanical energy and should be handled carefully during removal and installation to prevent snap-back injury. De-energize or fully relieve tension from the assembly before replacing the spring. Use appropriate spring hooks or pliers rated for the application load. Verify the replacement spring free length, OD, and end style match the original before installation.
